Create a release check list tool [sf#220]

[tomschr]

Reported by sknorr on 2014-03-14 15:23 UTC DAPS has quite a few subcommands that are useful for optimising/linting the resulting books, especially before a release. However, it is quite hard to remember running all of those before the release. The idea here is to have some mechanism to make sure they are run before a release. These are the commands in question:

• validate
• optipng
• checklink
• spellcheck
• stylecheck

However, four of the five tools (the exception being optipng) may make manual intervention necessary. spellcheck is interactive, even. Thus, this is not as simple as creating a command that executes all these commands after each other.

Proof of concept is now in the DAPS repo in contrib/preflight/daps-preflight.

THis is something that can easily be achieved outside of DAPS, WONTFIX
